' f7 Claims. (Cl. 259-8) This invention relates-v to a .mixirggdevilco and moreparticularly. to .a .device for mixing lliquids and/or solids.

vIn mixing various materials such asdilierent liquids With each other, diierentsolids with each Y other, or liquids with solids, such materials often require wide variations in vtreatment to bring object kof the invention is to provide a simple, efficient and highly variable device for mixing materials.

With this and other objects in View, -theinvention comprises a rotary elementsupporting a cup for materials to be mixed, apertured for the passage oi materials between the cup and the element and adjustable relative totheaxis of rotation of;y the element to vary vtheaction of the cup and element on the materials.

Qther objectsand advantages will be apparent from the following .detaileddes'cription when taken in conjunction with. the accompanying drawing, wherein v Fig, 1 is a, fragmentary vertical sectional View Qi the device, and.

Fig. 2` iS. a., fragmentary top vplan vieu/:of the device,

the present embodiment a rotaryI element lo., hailing a. material WorkingY surface ll., is in the form of a disk-.like table having a downwardly projecting, embossed portion l2 rigidlyA Afixed to a shaft I3: which extends through .a bearing I4 of a, bracket l5, upon which. the portion l2 rests, to support the elenlent. The bracket. l5 isA rigidly secured to the under side of a support. lwhich may be bench. or thel like. The bracket l5- has asecondbearing portion |78. in which a. shaft I9 is joalled, .the latter being operatively con- Iled tQ. any Suitable drive. means. (notshown) to. drive the element liJf,r through a pinion mountedupon the shaft llland agear 2 t mounted upon the shaft i3, in, any .desiredV constant or variable speed. l

The support I ii is aperturedfor a receptacle 25.,M the latter completely surrounding the element l,0 with av lower or bottom portion 216| tapering l downwardlyto an outlet 2,1, excepting adjacent the` embossed portion |12 of the element, where the bottom portion 26 is bent upwardly. in an open annular flange to allow free rotation of the element and prevent passage of the mixed-.materia/1.215 hereinafter described,.fr0m the receptacle otherthanthrough the outlet 2l; Suitable means (.notfsbownmaybe connected to thev outlet 21 togdjgegg the material; awayfrorrn the receptacle. Angle. members; S11-, arcuate in. generalcontour,

are employed in the present embodiment to secure the receptacle 2,5 to the support I6.

A cup 32, has a bottom portion 33 providing a surface 34 for cooperating with the surface Il of therotary element Il). to treat materials. A central aperture 351s formed in the bottomy portion 33 of the cup for vthe passage of materials from the cup to the surface I l and thusI between the.v surfaces ll and 34., A resilient handle 3-6 having one end fixed to the cup extends through a, slotted member 31 carried by the Wall of, the receptacle 25 and through an aperture in the said Wall to a, positionoutsidethe receptacle, Where,l a gripping portion 38 is formed for the manual adjustmentof the cup on the element. A screw 4tlor other suitable means is associated With; the memberlilto eng/,age the resilient handle 36 to lock it, withthecupgnany desired adjusted position Suitable means is provided to vary the effect ofthe surfaces H and 34'. on the material to be mixed by varying the force of the surfaces one` towardl another. In the prese-nt embodiment a weight'ftl is s lidably mounted on the resilient handle 35 by the aid ofv a longitudinally extending; slot 42 through the arm extends; .A thumb screw I3` disposed in a threadedaperture inthe-'Weight 4-I provides means for securing the solid 5| and a liquid 52. It should be understood l that solids or liquids may be disposed in both containers. simultaneously or other containers may be. provided to supply various types.v of. solids or various types ci liquids., or both,v to the cup.y

'A supply line 55 havingA a control valve 5t therein feeds a controlled supply of the material 5l to the cup, While a supply linev 51-V having an adjustable valve 58' feeds a controlledsupplyA` of the-liquid' 52v to the cup.

During the operation of the device the'shaft i9 is rotated by a suitable power source (not shown), causing rotation off the pinionv 29; the gear 21'-, the shaft 13'! andltheelem'ent lgvtlie cup Sli remaining stationary, it being held' by the members 31 and 40. The materials 5| and 52, through the aidl of the control valves 56 and 58, are fed to the cup in the proportions desired for the mixture and in suitable quantities to maintain a desired level of the materials in the cup. During rotation of the element the materials in the cup will pass through the aperture 35 to the surface I I of. the rotary element. The materials are then caused to move with the surface II but in so doing they must pass beneath the surface 34 of the cup. The surfaces II and 34, therefore, coact to mix the materials.

The elementVv surfaces, thus Varying the action of the surfaces on the materials.

The embodiment of the invention herein disclosed is illustrative only and may be modified and departed from in many ways without departing from the spirit and scope of the invention as pointed out in and limited solely by the appended claims.

What is claimed is: Y

1. A mixing device comprising a rotary element, a stationary cup for materials to be mixed apertured for the pas-sage of the materials to the I0 is rotated at a sumcient rate of speed tov cause'. 4'

the mixed materials on the surface II to move outwardly by centrifugal force, but this vmovement is lower than the speed of rotation of theft.

`varying the force of the coacting surfaces I'I and '34 on-e toward the other by adjustment of the weight 4I relative to the cup. For example, the cup may be -disposed coaxially with the element, 4that is, the cup may be positioned so that its vertical center line and the axis of rotation -of the element will be as one, at which position there will exist only a simple whirling action. In moving the cup from this position, at the axis of rotation of t-he element, toward the periphery of the element theeifect of the surfaces I I and 34 on the materials increases from 4the simple whirling -action to a violent agitation, the latter existing when the cup is positioned adjacent the periphery of the rotary element. This is all due l,

.to the f-act that the surface speed of the element "L vincreases from its minimum speed at its axis to `its maximum speedat its periphery. Still wider variations may be accomplished in the action of the surfaces II and 34 on the materialsrby adjusting the weight 4I which may vary its effect on the surface 34 from substantially noradded weight, when positioned adjacent the member 31, through increasing weights, as it is moved outwardly on the resilient handle 316, to its maximum effective weight when disposed adjacent the cup.

4The support 41 for the containers 45 and 4t is adjusted when adjustment is made in the relative position of the cup and the element so that the materials from the containers may pass into the cup. 5
